This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal working state will be affected, fuel dispenser which is harmful to staff’s health due to intensive n fuel dispenser oise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 fuel dispenser = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispenser There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

havistas and non- chavistas, although most of the latter do not support the opposition. The government s approval rating was only 14% in a recent survey by Hinterlaces, a polling firm. Many Venezuelans have hitherto been inclined to absolve Mr Chávez of personal blame. But their discontents provide scope for an independent candidate not identified with the discredited opposition. One who may try to fit the bill is Teodoro Petkoff, a onetime leftist guerrilla leader who was planning minister in the last pre-Chávez government and who is fuel dispenser now a newspaper editor. Since Mr Chávez controls al fuel dispenser l the institutions of state, and is spending a massive oil windfall, he is widely assumed to be unbeatable. But as the demonst fuel dispenser rations show, he does not always control everything that happens in his country. © 2006 . Colombia Unintelligent Apr 20th 2006 | BOGOTÁ From The Economist print edition A compromised secret police THE timing of the revelations—just weeks ahead of a presidential election on May 28th in which Álvaro Uribe is seeking a second term—was surely not coincidental. But that did not diminish their explosive nature. Earlier this month, several Colombian publications reported claims that the former head of the Administrative Security Department (DAS)—the secret police—had worked hand in glove with leaders of Colombia s right-wing paramilitaries to murder trade-union leaders and thwart operations against drug-traffickers. The allegations came in interviews with Rafael García, a former DAS official. He was arrested last year on charges that he doctored files on paramilitary chiefs and drug-traffickers wanted for extradition to the United States. He wants a plea bargain in exchange for testimony against the former head of the DAS, Jorge Noguera, whom he accuses of close links with paramilitary bosses on Colombia s Caribbean coast. The DAS had given the paramilitaries a list of labour leaders in that area to be targeted for murder, several
